What is the standard unit used for velocity in the example calculations?

• A. Feet Per Minute
• B. Meters Per Second
• C. Miles Per Hour
• D. Kilometers Per Hour

Answer: (A)

Velocity is distance divided by time. In the example, distances are given in feet and time is in minutes, so expressing velocity as feet per minute keeps the units consistent and the numbers easy to interpret within the imperial system used on the site. Using metric units like meters per second or larger time units like hours would require converting feet to those units, adding unnecessary steps and making the results less intuitive for this context. Feet per minute also provides convenient, practical values for typical on-site movements or airflow/velocity calculations you’d encounter in a construction setting.
